Add the extension to your CKAN .ini file:
ckan.plugins = ... vocabulary_services ...
Create the database tables:
ckan -c path/to/ckan.ini vocabulary-services-init-db
This will create the following two tables:
vocabulary_service
vocabulary_service_term
Update the database tables:
ckan db upgrade -p vocabulary_services
(NOT to be confused with the CKAN core vocabulary table)
A cron job needs to be set up to refresh the vocabulary sevices periodically based on each vocabulary_service.update_frequency setting.
ckan -c path/to/ckan.ini vocabulary-services-refresh
A secure vocabulary is an ecnrypted CSV that is not stored in the vocabulary_service or vocabulary_service_term
database tables.
To enable secure vocabularies, enable the secure_vocabularies plugin in CKAN .ini file, e.g.
ckan.plugins = ... secure_vocabularies ...
You must also specify a path to a secure vocabulary configuration file, i.e.
ckan.vocabulary_services.configuration_file = /etc/ckan/default/secure_vocabularies.json
... to be continued ...
